Crumpled graphene could provide an unconventional energy storage

Graphene paper, which is a material formed by bonding together layers of the two-dimensional form of carbon, has been found to yield new properties that could be useful for creating stretchable supercapacitors to store energy for flexible electronic devices, due to its large surface area per mass.

The finding is reported in the journal Scientific Reports by MIT’s Xuanhe Zhao, an assistant professor of mechanical engineering and civil and environmental engineering. It has robust properties, which is one of the strongest materials and by crumpling a sheet of grapheme paper into a chaotic mass of folds, they can make a super capacitor that can easily be bent, folded, or stretched to as much as 800 percent of its original size.
